Question 07 ls 2.9

I have 30K+ on my LS and it has developed a heating problem but not overheating.
The temp gauge used to ride between the 1/4 and 1/2 mark for the first 30K miles then started to fluctuate up to half on the gauge when I came to a stop light and then would go back down when I took off.
I have put in a new thermostat, water pump, clutch fan, radiator, temp sensor and no change.
Took to dealership and they stuck a 195 in it and made it worse so I have taken out the 195 and replaced with 180. It now rides at half and will fluctuate a little. It is in the 20's at night and 50's during the day, should not be indicating at that range.
Have changed out the Dexcool to Prestone and no change.
